Liquid level controller online store from Drurylandetheatre? Liquid level controller refers to the control of high and low liquid levels through mechanical or electronic methods. It Can control solenoid valves, water pumps, etc. So as to achieve semi-automation or full automation. There are many methods, depending on the choice of different products. The float type liquid level controller is composed of a magnetic float, a measuring tube, a signal unit, an electronic unit, a junction box and installation parts. Generally, the specific gravity of the magnetic float is less than 0.5, which can float on the liquid surface and move up and down along the measuring tube. A measuring element is installed in the catheter. It can convert the measured liquid level signal into a resistance signal proportional to the change of liquid level under the action of external magnetism. And convert the electronic unit into 4-20ma or other standard signal output.

The advantages of ultrasonic liquid level gauge are very outstanding. It is mainly reflected in the following aspects : Adopt non-contact measurement. It is not easily affected by the viscosity and density of the liquid. Of course, the ultrasonic liquid level gauge also has its own limitations and insurmountable defects. Specifically, it is mainly manifested in: There should be no obstacles under the sound wave. Because the ultrasonic liquid level meter uses the principle of sound wave reflection to achieve liquid level measurement. If there are obstacles, it will affect the ultrasonic emission, causing signal loss and affecting the measurement effect.

Due to the non-contact measurement, the measured medium is almost unlimited. It can be widely used to measure the height of various liquid and solid materials. The ultrasonic liquid level transmitter is composed of three parts: ultrasonic transducer, processing unit and output unit. Find even more information at non contact liquid level sensor.

The External Ultrasonic Tank Level Sensor adopts the sonar echo ranging principle. It overcomes the influence of the tank wall on the transmission of ultrasonic signals. It adopts advanced digital signal processing technology. It can truly realize non-contact, high-precision measurement of the liquid level in the tank. The External Ultrasonic Tank Level Sensor can output 4-20mA standard signals or output the measurement results to the upper computer (or secondary meter) through the RS-485 interface. It can meet the automatic control of the system.

What is ultrasonic level sensor? Ultrasonic level sensor is a monitoring instrument for measuring liquid height, tank height, and material position. The ultrasonic level sensor can adopt two-wire, three-wire or four-wire technology. The two-wire system is: power supply and signal output are shared. The three-wire system is: the power supply circuit and the signal output circuit are independent. When using DC 24v power supply, a 3-core cable can be used, and the negative terminal of the power supply and the negative terminal of the signal output share a core wire. The four-wire system is: when using AC 220v power supply, or when using DC 24v power supply. When the power supply loop and the signal output loop are required to be completely isolated. A 4-core cable should be used. Read more details at https://www.drurylandetheatre.com/.
